9 Claims.

This invention relates to improvements in'air supply mechanism for delivering air under pressure, as for inflating tires, and is particularly directed to an improved apparatus of the nature employing a reeling device for an air delivery hose.

It is the object of this invention to generally improve the fabrication of the pneumatic hose reel device; to provide an improved construction for the spool; to provide an improved device for securing the reel against rewinding when it is desirable to use the hose with a selected length extended, which device will be conveniently operable for quickly releasing the hose from set position to permit automatic complete rewinding; to

provide an adjustable braking mechanism for controlling the speed of Irewinding movement of the reel; to provide improvedadjustable spring return means for the reel; .to provide for air supply to the rotating spool without loss of air; to

2o provide a double support for the axle of the spool and improved mounting thereof; to provide for adjustment of the complete air supply unit fdr mounting the same in position with the hose extended in the most desirable direction, and to provide removable side panels for the reel frame.

Figure 3 is an enlarged fragmentary view of a portion of Figure 2, illustrating the exible air connection at the axis ci rotation of the reel.

Figure 4 is a fragmentary sectional view taken on line 4 4, Figure 2, detailing the catch mechanism for automatically. locking the reel with the hose in extended or withdrawn position.

Figure 5 is a sectional view taken on line 5 5, Figure 2, further detailing the hose reel.

Figure 6 is a sectional view taken on line 6 6, Figure 2, showing the brakes associated with the hose winding reel for slowing the rewinding movement thereof.

The hose reel structure describediin general includes a housed winding spool for a length of hose, which hose can be pulled from the reel to some considerable distance for iniiating tires etc.

- The reel is brake controlled for preventing undue rapidity in rewinding. Also, mechanism is ineluded tor automatically causing the reel to be latched in a series of positions with the hose drawn out, which mechanism is effective for release of the reel by a slight withdrawal and quick release of the hose.

The air connection is through the axial mounting of the reel. The entire hose reel structure includingthe lcasing is designed for adjustm it relative to its attachment bracket, so that thev hose outlet may be disposed for service at any one of a plurality of positions.

Referring to the drawings, the hose-reel casing or body is generally indicated at l0. A bracket l1 for mounting the casing is provided. The casing includes two side plate elements or spiders l2, each of which includes a central hub 12a, these 65 hubs being coaxially disposed for axial mounting of the reel. The side plates are joined and spaced by means of bolts 13 for screw-threaded rods including inner and outer plate engaging nuts 14 at each end. Removable circular cover plates 15 70 formed of sheet metal are attached against the sides of the side elements for covering the open work thereof since these side elements have spokes 16 connectingthe hub portions 12 thereof to rim portions 17 for accessibility during adjustment and'inspection. Thev side plate elements or spiders include extensions 18 attached to the4 bracket 11 by means of screws 19.

A sheet metal drum 20 is fastened around and spans the space between the side elements. The 0 edges of this drum are flanges as at 21 overhanging the edges of the side plates and lying against the inner faces thereof.

'I'he hose spool 22 includes a spindle 23 iixed thereto and supported in sleeve bushings 24 oi' the coaxial hubs 12'A oi' the side. plates. 'Ihe spindle is hollow through hall' its length for air supply purposes and a pipe 25 extends radially from theA inner end of the hollow interior `oi the axle and through a radial clearance opening 25* in the hub of the reel and openings 25h on the sides of the spool, and by means of appropriate ilttings 26 has the inner end of thehose 27 connected thereto.

At'the solid end of the spindle, for the purpose of securing end thrusts a ball bearing 28 is disposed in an axial recess in the end of the axle, the ball protruding suiilciently for contacting a screw plug 29 locked in place in the screw-threaded outer end of the hub bore by means of a wire clip 30 fixed in the hub and traversing the screw driver slot of the plug. The other end` of the spindle or the air intake end extends into an air chamber provided in the hub oi.' the adjacent side element. This chamber is provided by screwthreading a gland 31 into the screw-threaded counterbore portion of the hub over the extended end of the spindle, the gland being internally bored for entirely clearing the spindle. This gland 3l engages a packing gasket 32 in the bottom ofthe hub bore, maintaining the gasket in position'vagainst the spindle for. preventing leakage' of -`air along the axle surface.

'riphery of this chamber element includes an annular groove 33 connected to the internal bore by means of a series of radial apertures 34. The air supply pipe 35 is connected to the hub 12l by means of a nipple 35, the tap hole receiving the nipple being in communication with the annular groove. Through this arrangement the air isdelivered to the interior of the spindle without leakage, despite the rotative mounting of the spindle relative to the hub.

The spool is fabricated of the following parts: A hub element 36 including an attaching flange 37 is rotatively fixed tothe spindle axle by means of a key 38. The spool body is formed of duplicate circular plate sections, opposingly engaged on the hub element 36 and attached to the ange 37 thereof by means of bolts 39. The sections of the spool lie hat together at the central portions,

`but each includes a rounded offset 40 providing portions of the elements, which when assembled form an annular chamber for receivingthe coils lof the hose.

The outer ends of the plates making up the re are outwardly ilared as at 41 and the space provided for receiving the hose is slightly greater in width than` the diameter of the hose for working clearance. The narrow annular space causes the hose to coil withthe coils directly on top of each other, thatis, with directly superimposed coils. The outer or supply end of the hose includesqa nlling coupling device 42 of conventional character. A rubber ball 43 is slidably mounted on the hose and lies against a compression spring 44, the compression spring abutting a shoulder 45 adjacent the supply fitting of the hose.

The discharge end of the hose passes out of the reel frame throughs, laterally disposed outlet element 46 fixed to the drum of the reel casing. A plurality of rollers 47 are journalled on shafts 48 in the outlet fitting surrounding the hose, there being four rollers spaced at 90 around the hose -for guiding the hose and permitting withdrawal The outer terminal is .engaged overaterminalpin or stud 52 secured in the adjacent side plate of the reel body. 'Ihe spring is enclosed within a casing 53 formed by overlappin cup shaped casing elements 54 fitted over and secured to the hub of the spool.

ing surface of the spool.

outer or brakepivoting ends spaced apart. EachV braking unit includes a brake arm 58 fulcrumed on a pin 59 extended between and secured to the plate elements of each bracket. 'I'his brake arm carries a weight 60 on its outer end and a brake shoe 61 on its inner end. The weight consists of a sleeve-like element having an enlarged or knob portion 62 on its outer end and a shank adapted to be slipped over the end of the arm and adjustably secured by means of a set screw 63 therein engageable in any one of a series of transverse notches 64 in the brake arm.

The brake shoe includes integral pivot lugs 65 pivotally attached to the end of the brake arm and an arcuate shoe portion 66 including a brake band 67 onits concave side engaging the brak- Centrifugal force is eiective for throwing the weights outwardly pressing the brake shoes against the braking surface when the speed of rotation of the spool becomes too great. The application of centrifugal force is controlled by adjustment of the brake arm weights. A stop 68 is provided vconsisting of a lengthy of metal secured to the spool and including an outwardly extended portion on which 'the 100 weight rests. This stop limits gravity induced movement of the brake arm maintaining the brake band in close proximity to the drum.

The spool is adapted to be set in a plurality of positions with the hose withdrawn by means of centrifugally operated clutch elements 69. For this purpose a circular clutch element 70 is secured to the hub of the reel casing by means of screws. This element 70 includes a series of four notches 71 evenly arranged in its periphery. '110 The flange 37 of the spool or .reel hub 36 has pairs of spaced lugs` 72 extending from its outer face, the pairs being diametrically related relative to the axis of rotation of the spool. A clutch element retainer block 73 is fixed between each 115 pair of lugs and includes a cross groove 74 in itsv inner edge. These retainersgare fixed, in place by means of the bolts 39 which secure the parts of the reel or spool together. The clutching elements 69 are in the form of short rollers mounted 120 for radial movement in the grooves of the retainers and are adapted to engage in the cross notches of the clutch element secured to the reel frame. v

as indicated. m Figure 4, unwindmgrotation of tthe spool is clockwise. The notches in the clutch element, which is fixed and non-rotative. are inclined gradually in one direction to permit the rollers to move easily out of the groove` when the reel is moved clockwise for unwinding. On rewinding or anticlockwise movement, the rollers engage in the grooves and lie against abrupt shoulders 75 of the grooves preventing further spring. urged rewinding movement of the spool.

It will be apparent that only one roller is working at a time since the movement of the rollersinto engagement with the grooves of the clutch f element is gravity induced, it being noted that the spool will rewind to take in -all of the ho.`

Slow return movement however causes latching for a roller will drop into the groove and lie against the abrupt shoulder. Accordingly, rvit is possible to latch the reel at half turn positions due to the useof two clutch engaging rollers. f

The inlet pipe 35 for the reel has its outer end screwed into a tap hole 76 in the side plate of the frame on the inside thereof. After the reel unit has been installed as desired, a supply line 77 can be connected into the outer end of the tap hole as shown in Figure 5'.

The hose has its innermost coil secured against the bottom of the spool by means of acotter pin '78 inserted through the sides of the spol and overlying this c oil so that unwinding movement or extension of the hose is limited. 'Ihe air servicing unit herein described has been designed to permit adjustment of the hose outlet so that the unit can be mounted in any position, as for instance, on the wall, ceiling, floor, or-pedestal or under the floor.

The adaptation of the unit to a particular installation is accomplished by changing the circumferential relation of the unit mounting brackla screw driver or rod is inserted through the hole 79 in the sides of the spool, permitting the hose to rewind until the screw driver or rod engages against a spoke of the frame. If the hose connection cannot then be reached, the hose is permitted to rewind further so that the hose connection fittings 26 are accessible, whereupon the hose can be disconnected andV entirely removed from the spool. The nuts on the bolts 13 are then loosened and the hose outlet 46 is grasped and moved to the desired circumferential position relative to the unit mounting bracket. For ex-1 ample, if the unit is to be mounted as shown in Figure 5 of the drawings, for floor installation, the hose outlet extends horizontally with the outlet in proper position. The operator then holds the hose spool, removing the rod, thereafter turning the spool against spring tension until the hose connection is directly above or below the hose outlet. The hose is inserted through the rollers and connected to the pipe 25 by means of the ttings 26. After the connection is made, the

' spool is permitted to move inwardly for one complete turn only and the cotter pin is replaced.
